Circé-class Submarine (1925)
The ''Circé''-class submarines were a sub-class of the 600 Series of submarines built for the French Navy prior to World War II. There were four vessels in the class, built to a Schneider- Laubeuf design. They were ordered in 1925 and completed by 1927.Conway p.273 The four boats of the ''Circé'' class saw action during the Second World War, from September 1939 until the French armistice in June 1940. General characteristics The ''Circé'' class had a displacement of 615 tons surfaced and 776 tons submerged. They had an endurance of 3,500 miles at , with a maximum surface speed of , and a submerged speed of . Their armament was seven torpedo tubes (three forward, two midships, and two aft) with an outfit of 13 torpedoes. As with all French submarines of this period, the midships torpedo tubes were fitted externally in trainable mounts. They had a single deck gun and two machine guns, and were manned by crews of 41 men. Ships * was at Bizerta in June 1940. She w ...

French Submarine Doris (1927)
''Doris'' was a ''Circé''-class coastal submarine of the French Navy, in service from 1928 until May 1940, when she was sunk off the Dutch coast by the German coastal submarine . The wreck was rediscovered by Dutch divers in 2003. Construction and commissioning ''Doris'' was ordered as part of the 1923 naval program. Laid down by Chantiers de la Gironde at Bordeaux, France, on 1 February 1924 with the pennant number Q135, ''Doris'' was launched on either 25 or 26 November 1927, according to different sources. Sources disagree on her commissioning date, some claiming that she was commissioned on 26 May 1928 and one that she began her official acceptance tests that day and was not commissioned until 10 January 1930, when she was at Toulon, France. Service history When World War II began with Nazi Germany′s invasion of Poland on 1 September 1939, ''Doris'' was part of the 13th Submarine Division of the 5th Submarine Squadron in the 1st Flotilla of the 2nd Squadron a ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

Submarine Classes
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion of ...

French Submarines Of World War II
The French submarine fleet of World War II was one of the largest in the world at that time. It saw action during the war but had a chequered service history due to France's position at that time. During the conflict, 59 submarines, more than three-quarters of the fleet, were lost. Construction history After World War I France had a fleet of 36 submarines, in a variety of classes, plus 11 ex-German U-boats; these were mostly obsolete (all had been disposed of by the 1930s) and she was interested in replacing them. To this end the French Navy made plans for a fleet of vessels in three Types: Type I ocean-going / grand patrol; Type 2 coastal defence; Type 3 mine layers. At the same time, the major powers were negotiating an arms limitation treaty at the 1922 Washington Naval Conference. There was discussion of banning submarines altogether, and to outlaw their use (a course favoured by Britain) both France and Italy opposed this. However the conference did place restri ...

North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scuttling
Scuttling is the deliberate sinking of a ship. Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of self destruct, self-destruction to prevent the ship from being captured by an enemy force (or, in the case of a vessel engaged in illegal activities, by the authorities); as a blockship to restrict navigation through a Channel (geography), channel or within a harbor; to provide an artificial reef for divers and marine life; or to alter the flow of rivers. Notable historical examples Skuldelev ships (around 1070) The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge. Cog near Kampen (early 15th century) In 2012, a Cog (ship), cog preserved from the keel up to the decks in the silt was discovered alongside ...

Torpedo
A modern torpedo is an underwater ranged weapon launched above or below the water surface, self-propelled towards a target, and with an explosive warhead designed to detonate either on contact with or in proximity to the target. Historically, such a device was called an automotive, automobile, locomotive, or fish torpedo; colloquially a ''fish''. The term ''torpedo'' originally applied to a variety of devices, most of which would today be called naval mine, mines. From about 1900, ''torpedo'' has been used strictly to designate a self-propelled underwater explosive device. While the 19th-century battleship had evolved primarily with a view to engagements between armored warships with naval artillery, large-caliber guns, the invention and refinement of torpedoes from the 1860s onwards allowed small torpedo boats and other lighter surface combatant , surface vessels, submarines/submersibles, even improvised fishing boats or frogmen, and later light aircraft, to destroy large shi ...
